Preface The Asset Standards Authority (ASA) is an independent unit within Transport for NSW (TfNSW)

and is the network design and standards authority for defined NSW transport assets.

The ASA is responsible for developing engineering governance frameworks to support industry

delivery in the assurance of design, safety, integrity, construction, and commissioning of

transport assets for the whole asset life cycle. In order to achieve this, the ASA effectively

discharges obligations as the authority for various technical, process, and planning matters

across the asset life cycle.

The ASA collaborates with industry using stakeholder engagement activities to assist in

achieving its mission. These activities help align the ASA to broader government expectations

of making it clearer, simpler, and more attractive to do business within the NSW transport

industry, allowing the supply chain to deliver safe, efficient, and competent transport services.

The ASA develops, maintains, controls, and publishes a suite of standards and other

documentation for transport assets of TfNSW. Further, the ASA ensures that these standards

are performance-based to create opportunities for innovation and improve access to a broader

competitive supply chain.

This standard specifies the technical requirements for the installation of active transport links. It

has been developed from RailCorp standard ESC 530 Cycleways on the Rail Corridor,

Version 1.1.

ESC 530 is withdrawn with the publication of this standard.

This standard is a first issue.

Foreword This standard is intended to be used by competent personnel engaged in the provision of

services relating to rail infrastructure. Compliance with the requirements in this standard will

not, by itself, be sufficient to ensure that satisfactory outcomes will be produced. Personnel

providing services based on the standard need to bring appropriate expertise to the matters

under consideration.

In addition to the requirements of this standard, asset decisions shall take into account the life

cycle cost considerations specified in T MU AM 01001 ST Life Cycle Costing.

If, when using the standard, it is considered that the intent of the stated requirements is not

clear, a clarification should be sought from the ASA.

1. Introduction Active transport links (ATL) include footpaths, cycleways, and shared walking and cycle paths.

In certain locations, the rail corridor could provide an opportunity to develop active transport

facilities.

2. Purpose This standard specifies the design, construction, maintenance and disposal or decommissioning

requirements of active transport links within the TfNSW heavy rail corridor.

2.1. Scope This standard specifies the design requirements for two types of ATLs for use within the TfNSW

heavy rail corridor:

• Type1 – ATLs that are separated from the activities of the railway maintainer and the

railway operator

• Type 2 – ATLs that are not separated from the activities of the railway maintainer and the

railway operator

2.2. Application This standard applies to the design of new ATLs on the TfNSW heavy rail corridor.

The requirements of this standard are applicable to all parties involved in the design of ATLs.

If, when using the standard, it is considered that the intent of the stated requirements is not

clear, a clarification should be sought from the Asset Standards Authority (ASA).

5. Safety requirements The design of active transport links (ATLs) shall take into account safety considerations for

construction, operational, maintenance and decommissioning workers; and, for the potential

users of the ATL.

The Authorised Engineering Organisation (AEO) shall establish and implement a design

process system that manages safety across the full life cycle of the structure. The design

process system shall be developed with reference to TS 20001 System Safety Standard for

New or Altered Assets.

6. Heritage requirements The design of ATLs shall be compliant with the necessary heritage regulations as mandated by

the Heritage Act 1977 (NSW).

Where items of heritage significance will be affected by the design of an ATL, the following

requirements shall apply:

• the provisions of the Heritage Act for all items listed on the State Heritage Register

• the provisions of the State Agency Heritage Guide for all items listed on the state agency

Section 170 Heritage and Conservation Register

Identification and assessment of impacts to potential heritage items shall be obtained early in

the scoping and design stage of a project.

Designs for ATLs at or in the vicinity of heritage-listed precincts shall be developed in

consultation with the relevant approval authorities, including the nominated operator and

maintainer, the relevant RIM, and regulatory authorities.

The design of ATLs shall demonstrate how identified heritage elements have been considered

in the design before the construction stage. Consultation with local community groups may also

be warranted in particular circumstances.

7. General requirements All applications for development within TfNSW rail corridors shall be made through the Rail

Corridor Management Group (RCMG). An information and application package and the relevant

guidelines can be accessed via the TfNSW website.

The rail infrastructure manager (RIM) shall be consulted during the development of the

proposed ATL to ensure that:

• appropriate measures are included in the ATL to manage risks around the safety of the

users of the ATL

• appropriate provision is made for rail operations and maintenance

Impediments to railway operations shall be minimised as far as practicable. The interface with

railway operations, such as maintenance activities, generally requires complex management

arrangements in order to deal with safety issues.

ATLs within the rail corridor should be designed to be Type 1 ATLs, wherever possible.

The optimum arrangement is a Type 1 ATL located at the boundary of the rail corridor and the

boundary fence relocated to be on the trackside edge of the ATL.

An ATL can be fully Type 1; fully Type 2; or, a combination of Type 1 and Type 2 sections. The

extent of any Type 2 ATL sections shall be minimised.

In general, ATLs shall be constructed at grade. It is possible for structures such as bridges and

culverts to also be required. ATLs may be attached to existing bridges. These shall be designed

and constructed in accordance with the relevant transport standards as published on the ASA

website.

The configuration and operation plan for a Type 2 ATL, or an ATL incorporating sections of

Type 2 ATL, shall ensure that the users of the ATL are appropriately protected from the

activities of the maintainer or operator. This may result in disruption to the use of the ATL if it is

required by the RIM.

8. Urban design considerations Urban design shall be considered as part of the design of ATLs.

Examples of urban design aspects to consider include:

• accessible and safe circulation routes

• crime prevention through environmental design (CPTED) principles

• maximise usage and activity to populate and activate spaces

• provision of logical links to existing transport infrastructure and facilities, including to other

ATLs and bicycle storage facilities (consideration should be given to the potential for future

links through consultation with local and state government authorities)

• minimisation of environmental impacts, including potential for the inclusion of alternative

energy sources

• consideration of local qualities and character, including but not limited to local heritage,

landscape, public art, and community involvement

• promotion of infrastructure design that pursues an agenda of design excellence

• landscaping shall not be in conflict with the requirements set out in T HR CI 12105 ST

Vegetation Hazard Management in the Rail Corridor

9. Design requirements – Type 1 ATLs The design of a Type 1 ATL within the rail corridor shall comply with the guidelines of the Roads

and Maritime Services publication, NSW Bicycle Guidelines; and, the Austroads publication,

Guide to Road Design Part 6A: Pedestrian and Cycle Paths. Any proposed departure from

these guidelines shall be documented by the applicant and included in the proposal to TfNSW

via the RCMG.

A Type 1 ATL occupies the area adjacent to the rail lines and does not infringe on the

infrastructure service requirements as set out in ESC 215 Transit Space, which ensures access

to the railway infrastructure by rail, police and emergency personnel, and their vehicles and

equipment. This access is required for maintenance activities and emergency purposes and

shall be unobstructed at all times; that is, 24 hours a day, 7 days a week.

Depending on the site specific requirements of the RIM, this access may be provided on one

side of the rail corridor and to particular items of infrastructure rather than being continuous

along the corridor.

Refer to Figure 1 for details of the zone reserved exclusively for infrastructure service

requirements and Figure 2 for examples of possible arrangements for Type 1 ATLs at cuttings

and embankments.

11.1. Design stage documentation ATLs shall be designed by an AEO.

Crossings supporting the ATL shall be designed in accordance with AS 5100 Bridge Design.

The detailed drawings shall comply with TMD 0001 CAD and Drafting Manual, in particular

Section 1, 2 and 3. The drawings shall be provided by the applicant as part of the planning and

design process.

General requirements include a detailed site topographic survey and scaled drawings that detail

the following:

• the proposed location in plan view and railway kilometrages of the ATL, relative to the

railway boundary, tracks and other adjacent railway infrastructure

• the proposed reduced levels of the ATL, relative to the ground, track and other

infrastructure

• the details of the proposed ATL formation, pavement design, running surface, drainage,

fencing, access gates, pavement marking, signage and lighting

• the details of existing underground services as identified in the Services Search and any

proposed protective measures where applicable

• the location of all access gates and crossings

The applicant shall prepare and submit a detailed technical specification for the proposed works

for approval by TfNSW.

In the case of a Type 2 ATL or an ATL containing Type 2 ATL sections, the submission shall

also include a detailed risk assessment, an operation plan describing how the ATL will function

and the specification of responsibilities for ensuring safety of the various users. The risk

assessment shall assess risk against the risk criteria defined in 30-ST-164 TfNSW Enterprise

Risk Management Standard.

The applicant shall also prepare and submit the maintenance requirements for the ATL in the

form of a technical management plan, for approval by TfNSW, including periodic inspections of

fencing, pavement and drainage systems. The maintenance plan shall include a clear statement

nominating the responsibilities of the external party and the RIM for inspection and

maintenance. The requirements and high-level processes for the development of technical

maintenance plans are detailed in T MU AM 01003 ST Development of Technical Maintenance

Plans.

Maintenance and operational plans shall include the specification of arrangements for any

necessary pedestrian and cyclist detours including temporary way finding requirements.

11.2. Work-as-executed drawings Work-as-executed drawings shall be prepared and submitted to TfNSW by the applicant on the

completion of a new ATL. Any variations to the approved design drawings shall be clearly

marked.

All work-as-executed drawings shall be lodged in the TfNSW Plan Room.

11.3. Deed All approved ATLs shall be covered by an appropriate deed. The deed shall include all relevant

information including approved easements and construction and maintenance agreements.

12. Construction The construction of an ATL shall be undertaken in accordance with the approval granted by

TfNSW and the relevant engineering standards.

Construction of an ATL shall consider the effects the construction will have on existing railway

infrastructure.

12.1. Protection of rail infrastructure Particular care shall be taken during the construction of an ATL to ensure that adjacent rail

infrastructure is not disturbed or damaged. Potential construction issues include the following:

• track subsidence

• excavation at the base of railway embankments, which might lead to destabilisation and

failure of the embankment

• disturbance to drainage systems over railway cuttings, which might lead to failure of the

cutting slopes or fouling of the tracks below

• undercutting of the base of railway cuttings

• damage to railway cess drains and disturbance to the flow of stormwater runoff

• damage to train examination or staff walkway areas

• excavation adjacent to building, bridges or other structures that might undermine or

destabilise the foundations

• damage to above ground railway equipment such as signalling infrastructure

• damage to existing above ground or below ground services

• working in proximity to overhead wiring (OHW)

13. Maintenance The applicant shall implement the maintenance plan for the ATL in accordance with the deed

requirements. A copy of all inspection and repair reports shall be forwarded by the applicant, or

nominated maintenance party, to the relevant RIM.

14. Decommissioning or disposal Decommissioning is the final process of withdrawing an asset from active service on the

network.

Disposal is the process of removing an asset from the network. For example demolition of an

overbridge followed by removal and recycling.

The decommissioning or disposal of an asset is the final stage of the asset life cycle. Proper

planning of this part of the life cycle is an integral part of the strategic life cycle process.

The process to be undertaken for the disposal of an active transport link on the rail corridor shall

be as follows:

i) A report shall be produced to confirm that the asset is surplus to the requirements of the

rail network or it is life expired.

ii) The report shall identify the benefits including financial costs arising from the proposed

decommissioning or disposal.

iii) The report shall confirm stakeholder engagement regarding the proposed action. Such

engagement shall include, but not be limited to heritage, council and environmental body

consultation.

iv) The means of decommissioning or disposal shall be a risk based decision carried out in

accordance with the TfNSW safety management system. Refer to 30-ST-164 TfNSW

Enterprise Risk Management Standard for requirements regarding the mitigation of risk so

far as is reasonably practical (SFAIRP).

v) The report shall include a decommissioning or disposal plan for implementation.

vi) Following decommissioning or disposal, the asset database shall be updated to reflect

network changes.

95% of construction and demolition waste by weight of the decommissioned asset shall be

diverted from landfill.
